Donate to the Efficient Windows Collaborative

Energy loss through windows represents 4–5% of the U.S. total energy use consumption or $50 billion in annual energy costs!

The purpose of the Efficient Windows Collaborative (EWC) is to provide unbiased information, outreach and education, and disseminate research to the general public on the energy efficiency, technical, and human considerations that influence window and façade design, selection and use. The EWC collaborates with other organizations, educational institutions and government agencies that are working to promote energy efficiency in residential and commercial fenestration products.

The mission of the EWC is to lead and support — through the use of advanced window, façade and skylight technologies — the transformation of the built environment toward greater energy efficiency.
